I'm at a bit of a loss about the Kv/Voltage and amps(or Watts consumed). All the end numbers are pretty constant so why does it matter?
Using this T&P Motor, because it conveniently has the specs for KV/Voltage options and the corresponding Max Amps assuming input not output. For instance I can run an 800Kv motor on 12s (50.4V) and get 40,320 RPM. Or I can run a 600Kv motor on 16s(67.2V) and get 40,320 RPM. The input Watts are just over 15K for both. So what's the deal?
When I calculate [RPM = Kv*S*4.2V] the max RPM, for all versions, it runs about 37-40K.
I looked at the input power for a reference. When I calculate [Input Power(W) = Volts*Amps] the max input, for all versions, current it's about 14-1500 Watts.
In all cases the numbers are essentially constant. So why would I want a lower or higher Kv? Does the lower Kv give me more torque and quick acceleration, where the higher Kv would give me more top end power? But I could also use gearing to adjust the torque or top end back to why?
